Coming from an IT background to an AM transmitter site might leave you with a world of questions. Mark Persons explains the ...

These old 1N5305 current limiting diode regulators are simply constructed from a JFET with an internal feedback resistor to its gate which maintains a fixed current output.

By using a constant-current source along with a ratiometric DAC configuration, the output intensity of a laser diode can be carefully set and controlled using this simple circuit.

National 5 Practical electrical and electronic circuits Calculating the value of the series resistor Measurement and analysis of current and voltage in simple circuits allows us to formulate rules ...

Often, designers add series resistor R9 as a tool to measure and verify stability of the feedback loop. In production, this may be replaced with a zero Ohm resistor. The open circuit protection ...

A general-purpose I/O pin of a microcontroller charges a capacitor either by using it temporally as an output or by enabling a pull-up resistor, which is available in some controllers (Figure 2a).

This circuit provides different ways to measure the current-voltage phase displacement of a line-powered ac load. The classic approach for sensing an ac load's current requires ...

Flexible organic memory devices are promising candidates for data storage applications. Here, Ji et al.develop a flexible all-organic 64-bit memory cell array possessing one diode–one resistor ...
